We are given
sequence is 2 , 4 , 8 ,16 , 32 , .....
Firstly , we will check whether it is geometric sequence
Checking geometric sequence:
We will find common ratio between successive terms
and then we check whether they are equal
r1=(second term)/(first term)
r2=(third term)/(second term)
r3=(fourth term)/(third term)
r4=(fifth term)/(fourth term)
we can see that all four ratios are same
so, this is geometric sequence
Calculation of general term:
We got
common ratio is
Let's assume
number of terms is n
first term is 2
now, we can use formula
we can plug values
and we get
..................Answer
Call the length a, the width b
Perimeter = (a+b) x 2
And since we have (a+b) x 2 = 43.6, a + b = 43.6 : 2 = 21.8
a + b = 21.8
a - b = 7
-> a + b + (a - b) = 28.8
2a = 28.8
a = 14.4
b = 7.4
So, the area of the rectangle is 14.4 x 7.4 = 106.56
10. Find which one of the given fractions are value closer to 1.
First = 7/8
Second = 11/10
Let’s start solving
Let us start with the first value which is 7/8
=> 7 needs to be divided with 8
=> 7 / 8 = 0.875
Now, let’s solve the second value which is 11/10
=> same with first solution., divide 11 by 10
=> 11 / 10
=> 1.1
Thus, 11/10 is the has the nearest value to 1.
